[jira] [Created] (SAMZA-1773) Side inputs for local stores

Bharath Kumarasubramanian created SAMZA-1773:
------------------------------------------------

             Summary: Side inputs for local stores
                 Key: SAMZA-1773
                 URL: https://issues.apache.org/jira/browse/SAMZA-1773
             Project: Samza
          Issue Type: Task
          Components: kv-store
            Reporter: Bharath Kumarasubramanian
            Assignee: Bharath Kumarasubramanian


We want a way to populate the local store for jobs from a secondary data source (e.g hadoop), but is otherwise read-only. Typical use cases of such stores are scoring data for relevance jobs, etc

 

The rows (keys) in this dataset are independent of each other, and there's no requirement for the entire dataset to be updated atomically. This means that once the store is bootstrapped, it can be updated in change capture mode in the background while processing continues.
